1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Background: Ovarian cancer remains one of the most lethal gynecological malignancies, mainly due to late-stage diagnosis and frequent chemoresistance. Purpose: This study sought to develop 3D-QSAR models-Comparative Molecular Field and Similarity Index Analysis (CoMFA and CoMSIA)-to predict the antiproliferative activity of synthetic chalcone derivatives against A2780 ovarian cancer cells and to explore potential mechanisms of action through antioxidant response biomarkers. Materials and Methods: CoMFA and CoMSIA models were developed using a dataset of 64 chalcone derivatives and validated using q Results and Discussion: The CoMFA and CoMSIA models demonstrated strong predictive performance (q Conclusion: CoMFA and CoMSIA models accurately predicted the activity of synthetic chalcones, and the biological findings identify these derivatives as promising candidates for the treatment of ovarian cancer, including chemoresistant forms.
